To all whom it may concern:

Be it known that I, CHARLES M. DEWEY, of Jersey City, in the county of Hudson and State of New Jersey, have invented a new and Improved Puzzle, of which the following is a specification.

My improved puzzle consists in a plate, card, or like device provided with a square hole, a round hole, and a cross-shaped hole; and the solution involves the guessing of the Shape of a piece of material which will fit snugly in all three holes. A key to the puzzle, consisting of a piece of material which vsiill fit all three holes, accompanies the puzz e.

In the accompanying drawings, Figure 1 is a face View of my puzzle, and Fig. 2 is a perspective view of the key to the puzzle.

A designates aplate, piece of card, or piece of like material having in it three holes a, b, and c. The hole a is square, the hole b is round, and the hole c is cross-shaped.

The puzzle is to define the shape of a single piece of materiahwhich shall fit snugly in all three holes.

Serial No. 152,774. (No model.)

The piece of material which will fit in the three holes is square in one plane and round or circular in a plane at right angles thereto. These two portions being at right angles to each other form a cross. This is illustrated by the key,whioh is represented in Fig. 2.

I am aware that it is old to make a puzzle' O. M. DEWEY.
